NOTE: B grade products are in good condition, with all original packaging with either no cosmetic marks, or small ones. Comes with a 2-Year Yamaha warranty. Please feel free to request photos before purchase.

The XDA-AMP5400RK – the “AMP” – was conceived as a companion to the Yamaha XDA-QS5400RK as a way to provide additional speaker coverage and/or additional speaker output power in a custom integrated multi-room home audio system. It also pairs nicely with Yamaha AV receivers that offer Zone pre outs. The AMP packs eight channels of audiophile-grade amplification into a remarkably-slim 1U-high enclosure, allowing you to fully optimise your valuable rack real estate.

Feed up to four sources from the QS pre outs into the AMP – its four audio I/O buses can be patched together to handle a wide array of speaker/zone configurations. The AMP comes with a set of jumper plugs and cables, making it ultra-versatile right out of the box. The audio outs can alternatively be used to connect powered subwoofers or subwoofer amps.

When a QS and AMP are used together, simply wire the trigger ports to automatically power on/off the desired amplifier zones – no additional control interface is needed. The AMP also works great as a companion to an AVENTAGE AV receiver. When using the AMP with other sources, audio sensing inputs and an infrared I/O provide additional control flexibility.

Each of the four amplifier zones is also bridgeable, giving you the option to increase power output to select speakers if needed. The AMP employs ultra-efficient ICEpower integrated circuits to deliver eight channels of pristine, musically-dynamic digital amplification 50 watts/channel (8 ohms) with an outstanding 5 Hz to 40 kHz (+0/-3 dB) frequency response and 108 dB signal-to-noise ratio. It is 4 ohm capable at 100 watts/channel and bridgeable to 200 watts/channel (8 ohms). The AMP employs a balanced audio circuit design and PML capacitors, which are also used in Yamaha's flagship AVENTAGE AV separates. The result: greater realism and expressiveness for all of your favourite music.

As with the QS amplification, the curse of the custom integrator: the ground loop hum is gone, a common and vexing side effect of connecting a bunch of electronics together in a rack. The AMP takes care of it with a brilliantly-engineered differential circuit design. Sometimes it’s what you don’t hear that sounds the most amazing.

The AMP is truly made for custom integration, with Euroblock-style speaker connectors and a detachable AC cable for smart connectivity. The included magnetic faceplate discourages tampering and provides the perfect cosmetic finish. Mount it in a rack above the QS streamer - with the included ears or remove the ears for shelf installations and you have a slick, powerful and slim-line installation fit for the best of projects .
